Recording of molten lava slowly advancing forward at Kilauea volcano, Hawaii. The cooling thin crust of the lava and the movement produces constant popping and clicking like sounds. Some wind at the microphone disturbed the recording. Rare human sounds come from observers staying at the area. Recorded with Zoom H2n, postprocessing in Steinberg WaveLab LE (only normalization).

A great sound that I am using in lava levels my Android game "Web Raid Mobile" https://play.google.com/store/apps/details?id=de.agsteiner.android.webraidwhich will have sound in the next version. Thanks!
